Desal plant builder offers water quality assurances

The company building the desalination plant at Wonthaggi is reassuring Victorians that the quality of the water it produces will be within Government guidelines.

Questions have been raised about the amount of the element boron in the water that comes from the plant.

The chairwoman of the Aquasure consortium, Chloe Munro, says the reverse osmosis process removes minerals as well as salt.

She says it is the same process used by desalination plants around the world.

"But what we're doing is meeting standards set by Melbourne Water, so we've agreed with them that we will deliver water with a very high level of purity with no more than half a milligram per litre and as I say that is well below the Australian drinking water guidelines which allow for the natural variability of up to four milligrams per litre," she said.
